COTS (kots), n. 1. Commercial off-the-shelf. Terminology popularized in 1994 within U.S. DoD by SECDEF Wm. Perry’s “Perry Memo” that changed military industry purchasing and design guidelines, making Mil-Specs acceptable only by waiver. COTS is generally defined for technology, goods and services as: a) using commercial business practices and specifications, b) not developed under government funding, c) offered for sale to the general market, d) still must meet the program ORD. 2. Commercial business practices include the accepted practice of customerpaid minor modification to standard COTS products to meet the customer’s unique requirements. —Ant. When applied to the procurement of electronics for the U.S. Military, COTS is a procurement philosophy and does not imply commercial, office environment or any other durability grade. E.g., rad-hard components designed and offered for sale to the general market are COTS if they were developed by the company and not under government funding.

rying to figure out where government spending for the military is going is like trying to predict the strength and direction of the wind on a particular day years in advance. That’s really what users and suppliers need to do in order to position or re-position their organizations to be effective. The big guys try to influence or get a better read on the future military spending “wind” through lobbyists and any political influence they can muster. This hopefully allows them to rifle-shoot at a few targets. The smaller guys taken together are a lot like one shotgun blast—some pellets will hit but many will miss. Every year they all reload and take another shot. No matter which method used to shoot at the military spending target, some organizations will end up better than others. In decades past companies were more able to take a long-term approach to fiscal, marketing and product planning. Those were the days when corporate share holders were in for the long (or longer) haul. In contrast, today’s day trader and computer programmed stock trading has forced all but the largest companies to almost abandon long range plans for quarter on quarter returns. So if you are a less than $500 million company, how do you manage in this type of market? The reality is that most haven’t figured it out and in many cases some of those that have been successful have just been lucky. You know what they say: it’s better to be lucky than good. But if you want to be a successful organization in the military electronics market—and you aren’t going to base your future on luck—you have to grunge it out. That means a lot of work that takes time before you get a return. How does a company position itself to grunge it out? Most organizations just take their current technology and products and try to implement what they have. That really places them in a position requiring two strokes of luck: one that they have the best product for the program and secondly that the program makes it through to deployment. Other organizations perform quick-turn designs targeting a specific program. With this approach—if your organization is the successful bidder—you now just need to have the program get deployed in a reasonable time period. This design-for-program approach limits the number of programs you can bid and ties up a lot of engineering time and financial resources. That’s more than many companies can afford—remember the share holders. All of these issues are obstacles that have kept many commercial companies from venturing into the military electronics market. If you’re as large as a Boeing or Lockheed Martin you can have offices full of researchers and market analysts. If you’re a [ 6 ] COTS Journal February 2011
small company you need to have at least one person that is a voracious reader who can paint a broad mental mural of the future as it will relate to his organization. Elements in that mural will come from a variety of different pieces of information: the economy, politics, rhetoric from within the military, casual information from customer’s program personnel, program publications, systems and component publications and so on. You then develop a macro view of where things are going in the next 3-5 years. That mural now has to be a factor in all the different layers of planning a company has to do. We’re fully aware of how difficult this is. Our editorial team has to take into account all the underlying factors like the GCV, F-35, UAVs, the effectiveness of small embedded suppliers, the shift in structure of prime contractors, gaming technology, consumer electronics, the new Congress, cyber warfare, reshaping of each of the military branches and the DoD and so on. Some of us focus on individual elements and some try to blue sky the whole picture. Here are some whole picture blue sky thoughts to consider: the U.S. will stretch out the life span and effectiveness of every current system that the military has through upgrades at the expense of new programs. We will see a major increase in all technology to gather information and protect our technology and data. Politics will continue to screw up military programs— that’s a no-brainer prediction. Politics will also react frenetically to change the military to whatever internal or external whim of the day. A majority of the service brass will hunker down to resist legacy changes. Europe will cut military expenditures expecting us to pick up their load. China will become more problematic militarily while exerting greater influence on us economically. Believe it or not there are at least several issues in those blue sky thoughts that will have a significant effect on every reader— whether you’re a user or supplier. These are just some of the thoughts we’ve put together. Each and every company should put together their own. Then—as you consider developing components, subsystems or complete systems—you make sure that they will comply with your blue sky parameters.

Lockheed Martin Team Demos AMF JTRS Radio on Apache Helicopter A Joint Tactical Radio Internet Protocol (IP) communications network has successfully transmitted data and video to ground-based radios from its first airborne platform. The Lockheed Martin Airborne & Maritime/Fixed Station Joint Tactical Radio System (AMF JTRS) team, with support from Boeing, conducted this significant test that provides a
new capability to connect joint forces on the battlefield. This also marked the first airborne demonstration of AMF JTRS on board the AH-64D Apache (Block III architecture) helicopter (Figure 3).
In the demo AMF JTRS transmitted live streaming video and real-time situation awareness data from the Apache’s onboard infrared camera to ground-based radios. AMF JTRS will be a secure (NSA Type 1), software-programmable, multi-band/multimode, mobile ad hoc network that will give joint U.S. forces simultaneous voice, data and video communications. During the demonstration at Boeing's Mesa, AZ facility, Lockheed Martin's team integrated an AMF JTRS Small Airborne Joint Tactical Radio enabled with the Wideband Networking Waveform (WNW) onto an Apache helicopter. Ground and aerial nodes interfaced in a dynamic joint tactical mobile ad hoc network using IP-based communications. AMF JTRS then transmitted live streaming video and real-time situation awareness data from the Apache’s onboard infrared camera to multiple ground-based radios.

Special Feature 10 Technology Hurdles for the Military
Ten Technology Hurdles Facing Today’s Military Today’s embedded computer building blocks offer incredible capabilities, but packaging them for military platforms is more challenging than ever.
Jeff Child, Editor-in-Chief
lectronics and computing more than any other realm of technology are what give today’s warfighters the edge they need to succeed in their mission. But the task of adapting the latest and greatest advanced electronics to suit military needs is not without challenges. System designers are trying to squeeze more functionality into existing spaces or the same capabilities into smaller platforms. Meanwhile, in order to get the most out of today’s electronics and computer technology, military systems have steadily moved to implementing more and more of their functionality as software running on embedded computers. A GAO report last summer illustrated that trend in a table comparing military aircraft. In the F-111 aircraft of 1970, only 20 percent of its system functionally was implemented as software running on embedded computers. The F-16 (circa 1982) ran around 45 percent of its functions, and for the F-22 that grew to 80 percent. In other words, the percentage of functionality provided by software has increased tenfold over the past 40 years. That means not only are rugged embedded computers an ever more critical part of military platforms, but that the software complexity has skyrocketed as well. The appetite for ever greater embedded computing brings along a host of related challenges including system cooling, power management, component obsolescence and more. As a sort of “State of the Technology Union,” explored here are ten of the most daunting technology hurdles facing military embedded systems developers. Table 1 lists the ten hurdles.

processors with more integrated boards sporting FPGAs. In ground vehicles the computer density challenges are driven by the sophistication of onboard communications and control electronics. Those challenges are more acute than ever since the Army’s directive to armor all tactical vehicles to protect our soldiers from weapons such as Rocket Propelled Grenades (RPGs) and Improvised Explosive Devices (IEDs). The added weight of that armor dramatically reduces the weight budget left over for the onboard electronics. As a result, many system designs had to go back to the drawing board and integrate into a much smaller volume.
System Cooling To satisfy demands for greater compute density, system developers embraced faster processors and boards with more processors and processors cores. All that inevitably pushes power dissipation to the limit. In an industry where air-cooling using fans is only acceptable in limited conditions, all new cooling techniques are on the table. In UAVs environmental control systems
(ECS) aren’t needed because there’s no onboard crew. That’s driven platform integrators to look for alternative cooling solutions. Increasingly, direct spray is being viewed as an acceptable alternative to aircooling. Direct spray systems from Parker Aerospace were used in the Air Force’s Airborne Signals Intelligence Payload (ASIP) program on the Global Hawk UAV (Figure 1). Scaled versions of the ASIP are being designed for Predator and Reaper UAVs. While exotic cooling schemes have made some inroads, the defense market is risk-adverse when it comes to such revolutionary changes. At a more basic evolutionary level, board- and box-level embedded computing vendors have been steadily improving their conduction-cooling designs. A recent example on the enclosure side is Curtiss-Wright Controls Electronic Systems’ new technology for thermal management of rugged embedded computing enclosures called CoolWall. Tests using the company’s baseplate-cooled Hybricon SFF-6 enclosure showed a 2.4x increase in thermal conductivity at the chassis level (2.4x decrease in sidewall temperature rise) along with a 10 percent weight decrease as compared to aluminum construction. The technology is based on a proprietary mix-
TABLE 1: The ten most daunting system design challenges facing today’s military platform developer. Because all of these interrelate with one another, they’re not in any order of priority.
Compute Density Perhaps the most fundamental challenge facing military system developers is the drive to get more computing into smaller footprints. For example, large and medium UAV platforms such as Global Hawk and Hunter have a seemingly endless appetite for greater onboard computer density. The movement is toward more capable radar systems that fit into the same space, and in some cases more compact radar electronics to make room for other payload electronics. That often means replacing the multiprocessing of big, powerhungry boards based on general-purpose

ture of metal composite materials. It delivers its higher thermal conductivity at a weight significantly lighter than aluminum.
Power Management Reducing size, weight and power cuts across all aspects of system design, but power supplies and power conversion electronics play a direct role in a system’s power consumption and power management. At the same time, power components vendors continue to shrink the size and weight of their power supply and power converter offerings, while also enhancing those features critical to military systems such as good shock and vibration performance. In the realm of high-powerdensity DC/DC converters, the modular form factor, commonly referred to as a brick, continues to be the preferred building block component for any applications, commercial and military. These converters—usually characterized by high-frequency operation allowing them to achieve their small size, high power density and efficiency—come in thousands of combinations of input voltage, output voltage and power level. The other side of the coin is the emergence of lower power processors. New Intel processors like the Core i7, for example, have increased the GHz per watt available on military embedded computing products. Meanwhile sophisticated system management specifications designed into form factors such as OpenVPX and ATCA enable system developers to get a better handle on which subsystems are drawing power at the appropriate time.
Component Obsolescence As commercial and consumer system lifecycles shrink, the components used in those broad markets are facing ever shorter life spans. And because the military depends on the processors, memory chips and other devices designed for those areas, the defense industry continues to feel the ever-present burden of obsolescence—or Diminishing Manufacturing Sources and Material Shortages (DMSMS) as it’s called in defense circles. Today, end products in the consumer space are almost universally designed to be dispos-

The defense industry, in fact, remains one of the very few segments of the electronics market that actually repairs and upgrades its electronics subsystems rather than just throwing out the obsolete product. The good news is there’s an established infrastructure of companies and government organizations in the business of addressing the obsolescence problem. There are numerous after-market chip suppliers who stock inventories of obsolete device or redesign systems to emulate unavailable components. A review of these companies will be provided in COTS Journal’s Twelfth Annual End-ofLife Supplier Directory next month.
Legacy Subsystem Support The “problem” for military system developers has long been one of the most lucrative opportunities for military embedded computer vendors. Sometimes dubbed the “cash cow” of the military embedded computer business, slot-card technology upgrade programs are continuing to do brisk business. The VME form factor is the most successful enabler of this concept. That ability to insert new processing, memory and I/O functionality on legacy platforms is exactly why the military has favored modular slot-card form factors like VME in the first place. A host of deployed programs and long design cycle programs continue to demand VME SBC upgrades that drop into an existing slot with the latest and greatest processing
technology. The more recent technology hurdle is the challenge of using older installed legacy VME subsystems while still embracing the benefits of new architectures like OpenVPX. Billions have been invested in legacy VME systems, and it will be a long while before pure OpenVPX-only systems dominate. OpenVPX is expected to have a strong presence in military programs that have brand new embedded computing implementations—some of which already use VPX. But side-by-side will be a substantial number of hybrid systems—systems using both VME and VPX boards and subsystems. If a VPX system, for example, needs a piece of technology like an RF tuner, the system designer could implement a hybrid system that accommodates a VXS or VME version of the tuner. Hooks have been designed into the OpenVPX spec to enable such systems. Using a specialized bridge chip it’s straightforward for board makers to bridge between OpenVPX and VME.
Safety-Critical Operation The fact that military system functionally is now mostly software-based means that the burden of security and safety-critical operation falls squarely in the embedded software realm. Military and aerospace avionics systems have been early adopters of new standards along those lines. The size and complexity of avionics software is projected to grow geometrically. Such software has to be certified to the

idea of “GPUs as general-purpose processing engines” also falls nicely into the theme of doing more while keeping the complexity at bay—complexity to the system developer in this case. Graphics chip vendor NVIDIA developed a parallel computing architecture called CUDA. It lets programmers use conventional computing languages to access the massively parallel processing capabilities of the GPU. Aside from serving applications in radar, signals intelligence and video surveillance and interpretation, GPUs based on the CUDA architecture have potential in other application areas including target tracking, image stabilization and SAR (synthetic aperture radar) simulation. Board-level products have emerged specifically for GPGPU computing in a number of form factors including OpenVPX.

But while those efforts seem costly they pale in comparison to huge costs associated with correcting software defects once they’re deployed on an airborne system. Tool vendors such as LDRA Technology ease these burdens with a requirements coverage tool that integrates code review, data and control coupling, and code coverage tools. DO-178B guidelines include details on aspects such as ARINC 653 architectural robustness. Robustness, as defined under DO-178B guidelines, is a very specific proof that under all application failure conditions, a single failure in one partition will not affect other partitions. RTOS vendors like Wind River Systems know how challenging this is.

Managing Complex Multiprocessing The sheer complexity of today’s military embedded systems is overwhelming. The challenge gets particularly acute when systems run on a variety of processor engines. FPGA-based systems are an example. In contrast to generalpurpose processors, FPGAs don’t have a defined internal architecture, instruction set, data paths, or peripheral set. Some board vendors offer tools to ease that complexity—such as BittWare’s ATLANTiS FrameWork. It provides reconfigurable FPGA components, along with the infrastructure necessary to implement, simulate, synthesize, validate, and deploy a complete FPGA application on Alterabased products. A recent trend that’s emerged as a simpler way to do complex multiprocessing is the idea of putting high-performance graphics processors to work on general-purpose processing tasks. This
Thanks to the “magic” of semiconductor integration, the definition of a complete computing system has changed from a card-cage full of slot-card boards to a small box- or board-level solution. And while standards-based slot-card solutions aren’t going away, there are many military applications that need to eliminate every pound of weight and square inch of volume that it can. Generally speaking, a COTS rugged box system can be smaller, more power-efficient and more shock and vibration resistant than a slot-card solution. These complete system boxes— which often support standard form factor boards inside them—provide a complete, tested and enclosed computing solution that eliminates complex integration chores for customers. An example along those lines is the XPand4200 (Figure 2) from Extreme Engineering Solutions. This 8.8-pound sub-½ ATR, forced air-cooled enclosure for conduction-cooled modules measures 4.88 x 6.0 x 13.5 inches. On the board-level side, the demand for reduced size and weight has driven military system developers to consider non-backplane system architectures. One approach that’s gaining mindshare is the Computer-
on-Module (COM) concept. COM boards provide a complete computing core that can be upgraded when needed leaving the application-specific I/O on the baseboard. COM Express adds high-speed fabric interconnects to the mix. Just one COM Express module can provide the same processing and graphics performance as alternative solutions: like a multiple PC/104 board stack.
these include software and programmable radios, RF beamforming, ultra-wideband optical communications and IP networking on land, sea, air and space platforms. As one of the key parts of that networking, Ethernet has become entrenched as the favorite interconnect fabric in compute-intensive applications like sonar, radar or any application that networks sensor arrays together. At the board level Ethernet is being accepted as a fabric inter-
connect in its own right. But RapidIO and PCI Express still offer advantages when radar array processor or low-latency control is required. Mercury has connected the dots to that issue with its Protocol Offload Engine Technology (POET), which encapsulates standards-based protocol management, such as Serial RapidIO and PCIe, with high-speed real-time switching capability for any platform including Intel-based processors.
It’s clear that prime contractors are shifting to an ever greater reliance on embedded computing suppliers. They’re asking for integration expertise and a level of software development as part of those integration efforts. Driving that is the need for primes to contain their costs. Pressure to do that continues to ramp up as more and more programs are structured as fixedprice rather than cost-plus. DoD procurement policies are helping to drive increased interest in preconfigured subsystems from COTS vendors. The Weapon Systems Acquisition Reform Act passed by the U.S. Congress and signed by President Obama in 2009 demands more demonstration of new technologies. The policy also pushes for demonstrations earlier in the program development phase. Technologies used also have to show higher technology readiness levels (TRLs) than previously required. That’s helped drive demand for prepackaged and prequalified subsystems as primes find themselves without the time or the DoD funding to develop a prototype subsystem internally.
Complex Robust Networking As the U.S. military transforms itself to Network-Centric operations, every node in the networked military will be affected. The overall idea is for every vehicle (Figure 3), every aircraft, every ship, every UAV and every soldier on the ground to be able to quickly share data, voice and even video with almost any level of the DoD’s operation. A variety of technology areas are part of the overall puzzle to make that happen:

Power Issues in Board and Box Systems
Power Solutions Balance Density and Standards Support Though often an afterthought in the design process, power systems are a critical part of any military embedded system. New power supply and converter solutions offer ways to accommodate legacy military standards. Jeff Child, Editor-in-Chief
s military system developers demand more and more computing in ever smaller spaces, power has direct implications on the size, cooling and mobility of a system. Factor in the challenges of multi-voltage electronics and the complexity of distributed system architectures and it’s clear that military system designers need solutions that address those needs. Selecting power supplies and power conversion electronics rank as make or break technical choices in embedded military computer systems— even today it’s sometimes left as an afterthought. Responding to those demands, military power conversion vendors are crafting more efficient products, new partitioning strategies and increased ruggedization in order to serve board- and box-level military electronic systems. One of the trickiest problems faced with military power system designs is making the latest and greatest power supply and conversion technologies compliant to military standards. Defense applications must meet a number of noise and power related standards such as MIL-STD-461, MILSTD-704 (Figure 1) and MIL-STD-1275. Complicating matters, those standards have a number of revisions, any of which may be enforced by an application’s requirements. Addressing those needs, board- and

Tackling the filtering problem directly, Vicor offers its MIL-COTS VI BRICK Filter as a stand-alone filter or integrated with the PRM Regulator Module. The filter enables designers using Vicor’s MIL-COTS VI BRICK and V•I Chip PRMs to meet conducted emission / conducted susceptibility per MIL-STD-461E/F and input transients per MIL-STD-704A/E/F and MIL-STD-1275A/B/D. It accepts an input voltage of 16.5-50 VDC and delivers output power up to 120W. The integrated filter is 95% efficient and has a non-isolated regulator capable
of both boosting and bucking a widerange input voltage (16.5-50 VDC) and delivers output power up to 120W. The stand-alone MIL-COTS VI Brick Filter is a separate DC front-end module that provides EMI filtering and transient protection. Applications for the VI BRICK Filter are typically military ground vehicle and airborne systems. Examples of ground vehicle applications include communication, targeting systems, flat panel displays, RF jamming and GPS mobile tracking.

With that in mind, VPT offers its latest point of load (POL) DC/DC converter, the DVPL0503S (Figure 4). The 3A DVPL DC/DC POL converter can be used alone or in conjunction with the DVHE 50W DC/DC converter as part of VPT’s High Efficiency, Reliability Optimized (HERO) Power System. The DVPL 3A POL converter is a non-isolated, synchronous, buck regulated converter that steps down the voltage at the point of end use. Its tiny size and light weight save board space, weight and expense, making it an improved solution over the use of multiple isolated DC/DC converters to power individual loads in an electronics system. Military-grade environmental screening to MIL-PRF-38534 Class H is available.
High Power Solutions A significant portion of today’s military designs focus on networking and datacom types of gear. Powering such systems requires a unique set of reliability and high-wattage needs. Martek Power for its part offers the 12 VDC output version of the AHF series of 650 watts AC front end power supplies. The AHF series is a standard product line of high-density 12 VDC or 48 VDC output AC front ends with Active Power Factor Correction and 3.3 VDC auxiliary standby power.
Measuring 3.07” x 1.57” x 12.38”, the units deliver up to 53.3 amps across the full AC input range of 90‐264 VAC. With a compact 1U x 2U format, up to 5 power supply modules can be mounted in a standard 19” rack in a 1U high profile. Advanced design approach has maximized the power densities of the new AHF models to over 20 watt/in3, boosting efficiencies over 92%. Designed for Datacom and Network applications, the AHF models come standard with N+1 redundancy, which is ensured by hot plug and active current sharing scheme, and I2C management bus logic for system integration and communication features. Also targeting highly redundant datacom type military applications, TDK-Lambda provides a line of 1600W front end power supplies for use in distributed, hot-pluggable and redundant power systems. The HFE1600 series operates off a universal AC input of from 85 to 265 VAC, with active PFC, and provides a well regulated DC output of 12V, 24V or 48V. Operating efficiencies of up to 92% are typical. With the 19-inch rack-mount enclosure as many as five supplies can be paralleled with automatic load-sharing to provide up to 7600W of output power. A popular option is an integral MCU in each supply that allows for remote programming, monitoring and status reporting via an isolated I2C and PMBus interface. And, an “energy-saving” feature of the I2C/PMBus interface is that rack-mounted HFE1600 supplies can be individually turned on or off as the total system load demand varies over time. The HFE1600 supplies, each measuring only 1.61 x 3.35 x 11.8 inches, can be used individually or as many as five can be mounted in an 1U-high 19-inch rack enclosure to form a paralleled connected, load-sharing, hot-swap, N + M redundant 7.6 kW power system. Should a fault occur, each supply has an internal ORing MOSFET switch that will automatically disconnect it from the load and the other paralleled supplies. Plus, alarm signals and LED indicators are provided to identify a faulty unit. For added power, up to two rack-mounted enclosures can be parallel or series connected. Each HFE1600 supply has two variable-speed cooling fans and

Power Issues in Board and Box Systems
VPX Systems Face New Power Challenges Along with the much welcome processing and bandwidth benefits of VPX comes a slew of new complexities to managing power and power-related issues.
Jeff Porter, Senior Systems Engineer Dave Barker, Director of Marketing Extreme Engineering Solutions
here are many decisions a system architect needs to make during the design and development of an ATR system. One crucial component that is sometimes not given the attention it needs is the power delivery within the system. While this issue has always been a concern for ATR box design, it is especially true for VPX-based systems where increased processing and communication bandwidth, as well as improvements in thermal transfer capabilities, have lead to ever-increasing performance advancements and power input requirements for payload modules. Even though the VPX payload module’s P0 power (utility) connector allows for significant increases in power consumption over the older cPCI and VME connectors (Figure 1), thermal limitations will continue to limit the achievable power consumption per VPX payload slot. Since the processing requirements of today’s ATR systems have already surpassed the power input capabilities of VME and CompactPCI (cPCI) connectors, continuing advancements of the thermal transfer capabilities within the system will continue to push power con[ 26 ] COTS Journal February 2011

Limitations of VME and cPCI In traditional rugged ATR designs based on the VME or cPCI standards, MIL-STD-704 power supply designs and the power distribution of the system were
constrained by the limitations of VME and cPCI. However, for system designs that are based on the newer VPX standard, system architects have the ability to improve power supply designs and power distribution while at the same time reducing size and weight. There are two major developments driving the system architect’s ability to
Connector Issue Resolved
The VITA 62 specification defines a COTS plug-in power supply module for 3U and 6U VPX systems. Shown here is a 3D rendering of the XPm2120, a VITA 62 3U VPX power supply that will be available in 2011. improve power supply design and power distribution for VPX-based ATR systems while at the same time reducing overall Size, Weight and Power (SWaP): allocating 12V as the primary distribution rail across the backplane and using a COTS VITA 62 power supply within the chassis.
VITA 62 for VPX Power VITA 62 provides a standards-based plug-in power supply module (Figure 2) designed to support the needs of highperformance conduction-cooled VPXbased systems by resolving problems associated with older power supply standards. For instance, cPCI (PICMG 2.11) and VME (DIN 41612 Type M) power supply modules have three major limiting factors: no support for user-defined pins, no support for VITA 46.11 system management, and a limited amount of output power available for the 12V power rail. The inclusion of user-defined pins to the VITA 62 power supply standard encourages innovation within the industry by providing the ability for [ 28 ] COTS Journal February 2011
power supply designers to add additional features to their standards-based COTS power supplies as customer requirements and technological capabilities of power supplies evolve. VITA 46.11 System Management is also supported by the VITA 62 standard, providing the system’s management controller with access to features such as system power consumption and voltage levels at each power rail, as well as access to temperature sensors within the power supply module. Another significant issue with the cPCI and VME power connectors is that their output power pins are positioned on the opposite side of the backplane as a 3U VPX payload module’s P0 power connector. VITA 62 solves this problem and positions its 3U connector’s output power pins in line with the power pins on the VPX module’s power connector. This simplifies the power routing on the already spaceconstrained 3U VPX backplane and has the added benefit of reducing cost by removing unnecessary layers from the backplane.
The VITA 62 connector has resolved an additional problem specifically attributed to using the cPCI power supply connector in VPX-based conductioncooled systems. In order for the cPCI power connector to fit within the standard conduction-cooled slot, either the sides of the connector have to be shaved down or the guide rails for the power supply slot within the chassis have to be modified. Alternatively, a VITA 62-compliant power supply fits within a standard conduction-cooled 0.8- or 1.0-inch pitch VPX slot without modifications and also includes the standard VITA 46 key guides for commonality to other VPX cards within the system. VITA 62 recognizes the value of integrating some of the system design requirements that were formerly left up to the system architect. Two of these integrated features include hold-up and EMI filtering. By integrating these into the standard COTS power supply, the overall system design complexity and size can be greatly reduced. For instance, a power supply can be designed to boost the input voltage to a higher level internally in order to reduce the total bulk capacitance needed to maintain the required hold-up time of the system. This enables a power supply to potentially fulfill the entire hold-up time without the use of external capacitors, greatly reducing total system size, weight and complexity without having a noticeable impact on efficiency. EMI filtering can also be integrated into the power supply to address many of the EMI requirements needed for systems to comply with MIL-STD-461 and DO-160. Integrating EMI filtering into the power supply removes a great deal of the burden off the system designer, who would otherwise have to significantly overdesign their filtering circuitry or delay the design of their tailored filtering solution until the emissions profiles and susceptibility of the power supply were known and documented. As the result of VITA 62, conduction-cooled power supplies can now be implemented as true off-the-shelf products for VPX systems. This mitigates design, development and production risk because VPX-based ATR
boxes designed with VITA 62 power supply slots will support compatible power supplies from multiple vendors to be integrated into these systems.
12V Power Distribution Rail VPX, along with XMC, are unique within the industrial and military markets in that 12V has now become an option for the main power distribution rail across the backplane. For 6U VPX designs, 12V, 5V, or 48V can be used as the primary power path from the backplane. However, due to the many technical difficulties involved with generating and using a voltage as high as 48V within a VPXbased system, 48V is rarely used. For 6U VPX designs, 3.3V is not available from the backplane and must be generated locally on each payload module. For 3U VPX designs, the backplane can provide 12V, 5V and 3.3V to the payload modules; however, there are many technical advantages for using 12V as the primary power rail within 3U as well as 6U VPX designs. In legacy products such as cPCI, VME and PMC, a very limited number of pins are available for 12V power input and 3.3V is often heavily loaded from on-card devices. As a result the main distribution rail used to source power supplies on the payload modules is 5V. This leads to the power output of legacy power supply modules focusing on 5V and 3.3V and providing a limited amount of power available on 12V. These limitations on 12V output power from legacy power supplies has the unfortunate impact of either reducing the capability and performance enhancements of a VPX-based system or forcing the system architect to use a custom designed power delivery solution. Since lower voltage distribution sources, such as 5V, are heavily loaded and also tied directly to devices within the payload modules, this distribution method increases system susceptibility to on-card current transients (di/dt), causing a significant enough drop in voltage that could lead to component malfunctions and even module resets. Alternatively, when using 12V as the distribution power rail, susceptibility to current transients is greatly reduced because there is much less current draw when using this

Also, there are very few, if any, devices besides the oncard power supplies that use 12V directly, so if the 12V rail does dip, it will not lead to component failure.
Lower Voltage Sources Lower voltage distribution sources, such as 5V, require larger copper power planes within the backplane and modules in order to counter higher steady state currents and resulting increased distribution losses (V = IR). These larger copper power planes are also needed to counter the increased susceptibility to voltage drops from on-card current transients that result from using 5V as opposed to 12V as the primary distribution voltage. Higher voltage distribution sources, such as 12V, allow for the use of smaller copper power planes, which decreases board layer count, complexity and cost. Additionally, with higher voltage distribution sources, less point of load capacitance is required to suppress localized current transients, saving valuable real estate on payload modules. In most VPX- and XMC-based systems, 5V is not heavily used by on-card devices within payload modules and even
though many devices on payload cards use 3.3V directly, the load requirement is usually relatively small. Therefore, in the chassis power supply module the amount of circuitry dedicated to providing 5V and 3.3V for the backplane can be reduced with the focus put on maximizing the 12V output for the backplane, thereby increasing the total amount of power available on this primary power rail (Figure 3).
Legacy System Upgrades When upgrading a legacy system, many managers want to limit the scope of the risk to the project cost and schedule by reusing as much of the legacy system as possible. When upgrading a cPCI or VME system to use VPX modules, since the physical size, pitch (0.8â€?) and input voltage levels between VPX and legacy cPCI and VME modules are nearly identical, there may be a desire to reuse the power supply and chassis. However, attempting to reuse a legacy power supply within a VPX-based system limits the performance benefits that a system architect could achieve with VPX and could also create other unintended consequences. The inherent nature of new highperformance VPX modules bring with them additional system-level issues that February 2011 COTS Journal [ 29 ]
may have been less of a concern in legacy system designs. For example, many legacy power supplies are incapable of handling increased power load from upgrading to a VPX-based system. Also, because many VPX modules are designed using the latest power saving technology that will turn off or disable many higher power consuming features until they are needed by the application, the power distribution scheme within VPX systems needs to account for the significant di/dt that can result. Since legacy power supplies are usually incapable of supporting a 12V distribution rail, these transients can severely impact the capabilities of the system.
Problem with Custom Solutions Due to the limitations of older power supply module specifications, many legacy ATR systems used custom-designed power supplies to meet the needs of the system. Without VITA 62, many system architects currently defining their VPX-based design would be forced to go down the same painful path. A customdesigned power supply can be tailored to meet the power distribution requirements of the system today; however, if future system upgrades are needed, system component choices would have to be based on whether they are compatible with the custom power supply’s capabilities.
Designing a VPX-based system around a VITA 62 off-the-shelf power supply module and a 12V primary distribution rail not only allows the system architect to choose a power supply and distribution method that meets the needs of the latest available VPX technology both today and in the future, but also reduces the overall system SWaP. There is no doubt that VITA 62 does allow you to get the most out of your VPX system. Extreme Engineering Solutions Middleton, WI. (608) 833-1155. [www.xes-inc.com].

In the past, a power supplyâ€™s form factor and pin assignment varied from vendor to vendor because of the lack of standardization. Furthermore, due to the nature of the power supply, many were custom designed for the chassis that they reside in. PICMG 2.11 Positronics connectors and DIN 41612 connectors are commonly used for power supplies in the embedded environment; however, there is no standard pin out for DIN 41612 and thus the modules from different vendor are not interchangeable. PICMG 2.11 defines a pin out but is more geared toward

CompactPCI systems and lacks many of the advanced features of a VPX system (Figure 2). The lack of a pin out standard, as most electronic system integrators already realized, would practically lock the system design to a particular power supply vendor, which is highly undesirable from a logistics and costs standpoint. Instead, a nonproprietary mechanical and electrical standard opens up the opportunity for a wider supplier base, mitigates long-term supplier risks (e.g. product lifecycle issues and sole-source supplies), and reduces the overall program costs. According to Bruce Thomas, a member of the VITA 62 committee, the number one reason to use items designed to this standard is logistics. VITA 62 is an open standard, meaning that nothing at the interface is proprietary. â€œThere are many technical reasons for VITA 62. But the main driver is that system designers can purchase these modules from multiple COTS vendors to control costs,â€? says Thomas.
ules are designed to. VITA 46.11, System Management, is also directly supported. Figure 3 shows a simplified interconnect diagram of a VITA 62 3U power supply. The 3U and 6U connectors are designed to support high mate/de-mate cycles, which is important to support field maintenance. The VITA 62 connectors also feature high current carrying pins (40A and 20A) for the primary input voltage (DC/AC) and secondary voltages VS1, VS2 and VS3. A number of signal pins fulfill all other digital and analog interfacing needs. There are also plenty of User-Defined (UDx) pins for applicationspecific purposes. VS1 is typically used for higher voltages, like 12V and 48V. VS3 is 5V. The definition of VS2 is slightly different between 3U and 6U. In a 3U system, VS2 provides 3.3V. However, on the 6U, the VS can either be used as a 12V output or a 48V return. The 3.3V auxiliary voltage is mandatory to support VITA 46.11 operations. +12/-12V auxiliary voltages are optional in case they are needed to support low-power legacy hardware, like analog I/O PMCs. ENABLE and INHIBIT lines provide on/off controls on the primary and secondary side, respectively. SYS_RESET, Current Sharing (VSx_SHARE), Remote

Sense (VSx_SENSE), System Management (SMx) and Geographical Addressing (GAx) are also supported but not required. The FAIL discrete reports any failure. On the 6U, a Filtered Output is also provided for external holdup circuitry if needed. In a large system where more than one power supply is required, current sharing pins can be used to balance the power outputs between two or more similar modules. To support a system-wide nuclear event circumvention capability, an optional NED (Nuclear Event Detector) output provides a means to notify other modules in the system that a nuclear event is occurring and circumvention mechanisms should be activated.
Support for Onboard Intelligence Smart power supplies go a step further beyond simply providing system voltages. They provide system integrators with tools that are tightly coupled with the functionality of the power supplies, all within the modules themselves. Built-in features such as self tests, current/voltage/temperature monitoring, failure reporting, controlled power-up and power-down sequencing and nuclear event circumvention can be modularized to reduce the system development effort. The VITA 62 standard specifically supports future growth in this area. Conventional power supplies, on the other hand, only perform basic power conversion functions and would require external circuitry to support any control and monitoring functions, which take up valuable real estate elsewhere in the system as well as increase system integration time. With a programmable microprocessor, a smart power supply enables flexible and rapid development that scales to the functional needs of many electronic systems. To support this trend, the draft VITA 62 standard defines a modular packaging standard for 6U and 3U VPX power supplies, making true COTS solutions possible. While the basic functions of power supplies remain the same, a modular design that conforms to standard pin-out and form factor allows system designers to quickly connect the dots and build the system with confidence.
Self-Contained Smart Power Supply A self-contained smart power supply alleviates the need to put the power monitoring circuits, which require custom I/O and board area, elsewhere in the system. This allows the entire system to be designed using true embedded off-the-shelf building blocksâ€”such as SBCs, network switches, I/O modules and so on. To communicate with the host processor in a VITA 46.11-compliant systems, I2C-based IPMB can be used. For example, the microcontroller (IPMC) on board a power supply can continuously monitor the functionality of the module, and, in the event of a power failure, the host computer will be notified of the fault and allow it to react appropriately depending on the application. This is particularly useful in a large system. Internal to the module itself, Power Management Bus (PMBus) may also be used to communicate with now increasingly popular PMBus-enabled components, like power monitors, DC-to-DC converters, trims and power distribution modules. PMBus is an open standard drafted in 2004 by a coalition of industrial partners, including Texas Instruments. The PMBus forum became part of System Management Interface Forum, Inc. and is endorsed by the Point-of-Load Alliance (POLA) and the Distributedpower Open Standards Alliance (DOSA). To ensure interoperability and simplicity, PMBus is based on System Management Bus (SMB) protocol over an I2C physical layer, similar to IPMB in concept. The adoption of PMBus would further simplify power supply designs and free up board area for other features.
ment, current sharing, NED output and on/off controls. These new power supplies will allow system designers to concentrate on other aspects of their electronic systems, achieving quicker time-to-market. A VITA 62-compliant power supply not only simplifies system level designs, it also significantly reduces the lifecycle costs of the entire system. With custom and standard engineered system solu-
tions, a modular approach means that you can optimize and scale your power solutions for your specific needs. Curtiss-Wright Controls Electronic Systems Santa Clarita, CA. (661) 257-4430. [www.cwcelectronicsystems.com].

System Development Mobile Comms and Networking
Mobile Command System Hurdles: Space, Weight and Control Though created for the communications infrastructure market, ATCA is emerging as a key technology for mobile command/control communications systems. John Long, Product Line Manager RadiSys
One approach to overcoming this mobile command and control hurdle is designing military applications based on a preintegrated Advanced Telecom Computing Architecture (ATCA) platform. This offers higher performance than traditionally used commercial COTS technologies such as VME, CompactPCI or VPX, and offers computing, switching and storage in one easy-to-manage platform as opposed to equivalent rackmount server (RMS) systems. These ATCA systems present the ideal solution for developing computing and communications systems for ground mobile operations.
hen comparing the military of today with the military of old, the technological advancements are astounding. Gone are the days of commanders shouting orders or using smoke signals from a hilltop to command the legions. Today’s defense indusd try and military operations present a far more complex picture.

for bandwidth-heavy applications in the telecom industry, is being adopted across the defense industry. The transition to network-centric warfare has meant that military application developers now encounter many of the same challenges faced by telecommunications. The ATCA architecture offers the modularity, fieldproven reliability and performance required for today’s ground mobile applications and, as an open-standard platform, offers maximum flexibility for designing the latest in cutting-edge applications. With high-performance pre-integrated ATCA platforms specifically designed for mobile command and control available on the market, ATCA is becoming the ideal platform for designing today’s applications.
High Performance in Limited Board Space Advancing technology continues to allow greater performance to be integrated into smaller systems, and manufacturers are witnessing an industry-wide shift toward smaller, more compact designs. However, there is one place where bigger is still better: at the board level. Designers still require enough board space to incorporate the latest processors, chipsets, memory and
graphic processor units (GPUs) to create truly advanced systems that can support the latest in command and control applications. With so many military standards available, board space can be the differentiating factor when selecting a solution (Figure 2). ATCA offers a significant size advantage over other open standard COTS solutions, allowing for improved overall performance. With 2.7 times the board size of VPX or CompactPCI boards, ATCA affords developers more room to integrate the performance capabilities required for ground mobile applications. Today’s mobile military environment is demanding lighter, more compact designs. It is critical that military units be able to reach their destinations quickly; for this to happen, their computing and communication equipment must be highly portable. This places a premium on reducing system weight without sacrificing on performance.
Today’s command and control stations oversee the execution of orders across multiple peripherals in the field.
Improved Mobility in the Field
Standard Form Factor
Board Power Consumption
By designing on ATCA-based systems, developers can deliver significantly lighter command and control stations that allow for improved mobility in the field. ATCA computer modules offer capabilities and processing power comparable to RMS servers built on multicore server class processors. However, unlike RMS servers, ATCA is a bladed architecture, allowing multiple ATCA modules to be incorporated into a single chassis. Since the ATCA blades share a common enclosure, fan and power supply, they offer a simpler architecture that weighs significantly less than comparable solutions. For example, the RadiSys Promentum C2 Server (Figure 3) is a pre-integrated, portable ATCA platform specifically designed for ground mobile applications, and delivers a 33 percent weight advantage over equivalent RMS systems. With an average weight of 46 kg, the C2 Server is light enough for two people to lift, while an RMS solution delivering the same performance and memory weighs up to 85.8 kg. This weight savings directly translates to improved field mobility for a tactical advantage to military troops.

Comparison of board space and power consumption for standard form factor solutions in the mil/aero industry. The successful management of ground peripherals—including radar systems, unmanned vehicles and troops— requires locating, collecting and analyzing data in real time. For example, radar images need to be analyzed by state-ofthe-art algorithms to identify targets amongst the wealth of information. Audio and video data generated across thousands of square kilometers must be scrutinized for outliers, patterns and targets of interest. Once all this information is collected and scrutinized, directions must be transmitted to peripherals and implemented. To process the multiple streams of incoming and outgoing information, these control systems require the latest in high-performance computing,
high-end graphics and storage capacity (Figure 4). Today’s ATCA solutions are designed to offer the flexible, high-performance computing power required for command and control operations in an easy-to-manage platform. For example, the C2 Server can support up to eight Intel 5600 series server-class processors and 4 Terabytes of storage, delivering the ultimate in compute processing. A more balanced configuration could support two compute processing blades and two storage blades, with a total platform storage of 8 Terabytes. The addition of VMware ESXi allows for multiple operating systems, consolidating multiple applications into a single, carrier-grade February 2011 COTS Journal [ 37 ]
The Promentum C2 Server delivers high performance with a 33 percent weight reduction over comparable rackmount server solutions. blade. The increase in graphics and computing capabilities translates to more informed decisions and tighter control over operations. ATCA-based applications provide operators with additional ongoing management capabilities to maintain the overall health and performance of field-deployed systems. Industry standard protocols, such as Intelligent Platform Management Interface (IPMI) and Hardware Platform Interface (HPI), allow operators to remotely monitor, diagnose and debug multiple systems in real time without being exposed to unnecessary dangers. Obsolescence can be addressed through efficient and costeffective technology insertion; as processor and I/O technology continues to advance, older ATCA blades can be easily updated with the latest versions for cost-effective and quick-fielding performance upgrades. This allows the systems to remain relevant with lifecycles of a decade or more.
Pre-Integrated Platforms In addition to the design challenges of mobile command and control, developers need to be able to get their technology to the field quickly. Using a pre-integrated system specifically designed for mobile command and control [ 38 ] COTS Journal February 2011 Untitled-7 1

allows system developers to speed the design process. Pre-integrated systems are offering a new level of management and development capabilities, providing developers with greater ability to select the level of engagement needed on a per-project basis. They also offer thirdparty validation and a single point of responsibility for system integration; instead of devoting time and resources to integration, developers are able to focus on their value-added applications. This approach significantly reduces time-tomarketâ€”in some cases moving from concept to field deployment in a few months rather than a yearâ€”without any increase in project risk. Because of these enormous benefits and improved efficiencies, pre-integrated systems are becoming the new building block for military systems. Rapidly evolving technology is improving command and control capabilities, providing military personnel a comprehensive understanding of what is occurring in the field. From improved video and graphics capabilities to enhanced processing performance, the increase of information being collected is translating to more informed decisions and tighter management over military operations. Collecting this data and translating it into actionable information
requires advanced systems that offer large board space, lightweight options and enhanced control capabilities. With advanced support for each of these features and capabilities, developers are increasingly recognizing ATCA as the ideal solution for these unique mobile command and control challenges. For manufacturers developing next-generation command and control stations, preintegrated ATCA platforms are the ideal solution for tackling the space, weight and control challenges of today’s military operations. These improved command and control capabilities are advancing the modern military landscape and laying down the foundation for future military successes. Figure 4

Technology Focus Conduction-Cooled cPCI Boards
Conduction-Cooled cPCI Provides Here and Now Solutions Entrenched now as one of the mainstay form factor options for embedded military computing, CompactPCI continues to maintain a solid market niche. Like VME, cPCI now enjoys a wide set of board-level solutions. Jeff Child, Editor-in-Chief
o embedded computing form factor can achieve overnight success in the military market. Real acceptance into deployed programs takes years. But with nearly two decades now under its belt, CompactPCI can claim to offer all the aspects that pass the test for military decision makers. And though cPCI isn’t ever expected to eclipse the legacy of VME in the military market, its niche remains solid. An expanding set of conduction-cooled CompactPCI boards has emerged, some even from outside the usual crowd of conduction-cooled board makers. Among these are a wide collection of cPCI products that are available from a variety of vendors in every category including single board computers, I/O boards, slot-card power supplies, storage subsystems, mezzanine carriers, DSP engines and many others. The “Conduction-Cooled cPCI Boards Roundup” on the following pages showcases some examples of the current crop of conductioncooled cPCI single board computer products. In many cases, this group of cPCI boards includes air-cooled versions that offer a companion conduction-cooled version that’s electronically an identical design. Over the years, the PCI Industrial Manufacturers Group (PICMG) developed performance upgrade paths for cPCI, such as PICMG 2.16 and CompactPCI Express. A year ago PICMG adopted the PICMG 2.30 specification, called CompactPCI PlusIO. This new specification adds PCI Express, Ethernet, SATA, SAS and USB extensions to the CompactPCI family of specifications, while preserving PCI bus connectivity. The next phase of that effort is a second spec called CompactPCI Serial (PICMG CPCI-S.0) that defines systems built completely on CompactPCI Plus. It is currently in final review with PICMG. The attraction to CompactPCI—particularly in its 3U size—is striking in military applications where the mix of size constraints and demand for sturdy slot-card style ruggedness is called for. In many case, 3U CompactPCI is delivered to customers in complete integrated systems—a trend that melds nicely with the emergence of “stand-alone rugged box systems” as a product category among military embedded board vendors. Also fueling that trend is consolidation in this industry to the point where the larger corporations can [ 40 ] COTS Journal February 2011
Army soldiers test network gear for the BCT Modernization program at White Sands Missile Range. provide the entire computer, I/O and enclosure needs themselves. Over the past several years a growing number of vendors have made public announcements of military and aerospace design wins for their conduction-cooled cPCI products. Last fall, for example, GE Intelligent Platforms received the first in a series of orders that are expected to total approximately $2.5 million from General Dynamics C4 Systems for a quantity of GE’s rugged NETernity 3U CompactPCI CP923RC-M Ethernet Switches. The switches will be used as the communications hub for command and control systems deployed as part of the U.S. Army’s Brigade Combat Team Modernization (BCTM) program (Figure 1). The technology provides fast, reliable data interchange between computing subsystems on a range of vehicles including unmanned air and ground vehicles. BCTM is the U.S. Army’s principal modernization program. Its purpose is to build a versatile mix of mobile, networked BCTs that will leverage mobility, protection and information to conduct effective operations across the spectrum of conflict.

A popular strategy for military embedded system developers is to use one version of a board for development and then another more ruggedized version for deployment. Along such lines, ADLINK offers it highly integrated cPCI6510 series that supports optional extended temperature ranges and incorporates two PMC sites and DDR3 memory with ECC. The cPCI6510 series of 6U CompactPCI blades features a 32 nm Intel Core i7 processor with 2.53 GHz clock speed and up to 3.2 GHz maximum turbo frequency. The CT-61 is a rugged conductioncooled version of the cPCI-6510 (shown) with identical electronic design.
CompactPCI, particularly in its 3U flavor, has carved out a large chunk of adoption in the military realm. Aitech Defense Systems has released a new rugged 3U single-slot CompactPCI SBC that offers up to 8 Gbytes of onboard SATA flash disk storage. The C800 combines the latest low-power Intel Core 2 Duo technology featuring data processing capabilities of 1.67 GHz or 2.20 GHz and Intel’s Speedstep dynamic frequency switching that provides multiple lower power and cooling options with highly integrated on-chip L1 and L2 caches as well as the Intel GM965 Express Graphic Chipset.
FPGAs and DSPs working together form a powerful weapon for advanced signal processing applications. Exemplifying that trend is BittWare’s GT-3U-cPCI (GT3U), a ruggedized 3U CompactPCI board that has been designed for demanding multiprocessorbased applications.

Modular PXI Solution Targets CAN Communication The CAN bus has become an accepted technology in military systems, particularly in vehicle applications. GOEPEL Electronic recently introduced PXI 6153, a modular communication controller for CAN, based on the powerful, well established Series 61. The scalable architecture provides an extensive range of options for individual and flexible controller configurations and functional upgradability at a later date. The basic configuration features two separate CAN communication interfaces. Optionally, they can be extended with up to four additional ports (CAN, LIN/K-line, FlexRay). The result is a multitude of configuration and application opportunities, from testing routing functions at Gateway ECUs to parallel testing several ECUs in Run-In and Screening Test systems. The module is hence able to replace several conventional interface devices during the configuration of complex test systems. In addition to reduced purchase costs for test system configurations, fewer slots in a PXI rack than normal are required, allowing for future expansion.
